The first Dyno was done like August of last year and the second one was done yesterday. I'm wondering if elevation has anything to do with it since it was done at 5k above.

Those are corrected numbers, so no. Those are what your car might've actually made at a lot lower DA on a nice day. If you want to see what it's actually putting out in your location, look at uncorrected numbers. They'll be a lot lower, as you should expect at that altitude.

well, it looks like the map2 run (where you manged to get 14+psi) the IATs were in the 120+ range so I doubt it will make power there regardless of boost - what was the blower used by the dyno operator? And when you look at WGdcs, they are approaching 60+ as the rpm goes above 4600 (on either run). That is also when you begin to see a large delta on boost target vs mean. That tells me these snails are starting to show some age. Either that or you need to check vacuum hoses and boost solenoids...

You say the IC was installed before the dyno? as in JUST before? you probably had some adaption issues still going on.

So, what is the age of this n54? You got waste gate rattle? I doubt you will be able to make much more boost without some scroll work..

The other thing is this is a mustang eddy current dyno. At a min they are 10 percent below the avg dynojet.

Also to answer you're earlier question, the FMIC was installed just before, so i did wonder if this would effect its initial ability to cool.. it works like a dream now, and IATs actually drop after a pull.

Thx for your help.

I think the culprit might be the stock diverter values on the aftermarket charge pipe.. Will need to look at aftermarket ones I suppose?

im guessing you did the dyno at RG ?? i got my fmic installed as well just before i did my dyno and with e25 map mhd i had 412whp and 450 torque at 16.5psi ... no downpipes, stock air box, only tune and a vrsf fmic

i had no issues with high IATs even though fmic was installed minutes before doing the dyno

Duty Cycles. Short for the amount of time the Waste Gates are closed to try to make boost at the target level. As they age they have to stay closed more. And that will eventually cause WG rattle if you use the higher boost frequently.

Yeah it was at RG. I assume your numbers are also dynojet corrected? I know RG usually shows low numbers, but your numbers confirm the fact i'm running significantly less than i should be considering everything. Would be curious to see if numbers would change dramatically having the IATs at a more normal rate.

Do you have a log or a dyno graph for comparison purposes?

i posted one of 3 runs ...

i dont have a log since the dyno sheet doesnt show a date and since i got nearly hundred logs it would be impossible to figure out which one it was

i also had issues with my boost solenoids so it was never hitting 18 psi...always around 16ish... i had a check engine light pop up on one of the runs....
now im at 21 psi with a custom tune for the past few months... runs strong... no check engines... i also added a DCI intake so i might dyno it again soon
